1pm5 Summary


Crystal structure of wild type Lactococcus lactis Fpg complexed to a tetrahydrofuran containing DNA

The structure was published by Pereira de Jesus, K., Serre, L., Zelwer, C., and Castaing, B., in 2005 in a paper entitled "Structural insights into abasic site for Fpg specific binding and catalysis: comparative high-resolution crystallographic studies of Fpg bound to various models of abasic site analogues-containing DNA." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.95 Å and deposited in 2003.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely DNA (5'-D(*CP*TP*CP*TP*TP*TP*(3DR)P*TP*TP*TP*CP*TP*CP*G)-3'), DNA (5'-D(*GP*CP*GP*AP*GP*AP*AP*AP*CP*AP*AP*AP*GP*A)-3'), and Formamidopyrimidine-DNA glycosylase.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotrimers.
